Mid-Term Exam Review: Biology
Congratulations! You’ve made it halfway through the school year and are now ready for “Finals
Week.” The key to a successful end to this semester lies in preparation. Making sure you are
mentally prepared to take final exams will help ensure that you do well. Review your old tests
and quizzes, skim your textbook, and study this review sheet. If possible, study with a friend
(after you have studied on your own, that is). Take advantage of the classroom time allowed for
studying. Below are a few points to remember:

You will be awarded 10 extra credit points for every old test and quiz from this
semester. Find them, study from them, and then turn them into me on the day of the
exam for Biology Gold!!
Make sure you complete the entire review. Your review is worth 50 points – counted
towards your 2nd quarter grade (under tests, quizzes and large project category, which
is weighted more heavily than homework/assignments category). This review is due when
you walk into your biology exam. I will not accept late reviews.
Study from your review. Don’t just commit items to memory, understand major concepts!
Try explaining the concepts to a younger sibling or parent. Talking over concepts out loud
not only organizes your thoughts, but also shows you clearly where confusion may lie.
Your test will be all multiple choice, approximately 140 questions. You will be better able
to complete this test in the time allotted if you know the material.
Don’t leave any questions blank, answer all the questions even if you have to guess (a
guess is at least a 25% chance!)
Read the “stem” of the question and try to answer it first without looking at the choices.
Make sure you understand what the question is asking.
Then, read each choice carefully and try to eliminate options in the question that you
know are wrong. Narrow down your choices if you have to guess (now, you may have a 50%
chance of getting question right!)
Most importantly, get a good night’s rest AND eat breakfast (some protein – eggs, bacon,
or even a bit of peanut butter) before each final. Relax and have confidence in yourself!
Trust what you know. Don’t sweat what you don’t know.
IN ORDER TO RECEIVE EXTRA CREDIT POINTS ON YOUR FINAL EXAM, YOU
MUST BRING AS MANY OLD TESTS AND QUIZZES TO THE FINAL THAT
YOU CAN FIND.
***This review must be turned in the day of the exam
Late Reviews will not be accepted.***
